Retail employees in Study 1 and employees from multiple organizations in St
udy 2 completed a questionnaire investigating the moderating effect of perc
eived organizational support (POS) on the relationship of employees' fear o
f exploitation in exchange relationships (reciprocation wariness) and their
in-role and extra-role job performance. When POS was low, reciprocation wa
riness was negatively related to in-role and extra-role job performance. Wi
th high POS, reciprocation wariness was positively related to extra-role pe
rformance and either positively related to in-role performance (for retail
employees) or showed no reliable relationship with in-role performance (for
the multiorganizational sample). In deciding on their work effort, recipro
cation-wary employees considered how much the organization values their con
tributions and cares about their well-being. Implications for employee-empl
oyer exchange relationships and workforce cynicism are discussed.
